Airport Express disappears from Airport Admin Utility

If I power cycle my Airport Express, it correctly finds my (non-Airport) wireless network and its light turns green. It successfully works with Airtunes, and also works as a wireless bridge to my TiVo. However, after a period of time (usually a few hours), it starts flashing orange, and can't be found by either Airport Admin Utility or iTunes. However, it still successfully bridges the TiVo to my wireless router. Does anyone have any clue what's going on? If I power cycle it again, it goes back to green for a while, but it seems it can't refresh part of the connection without a power cycle.
I should also add that when I first set it up I had major Airtunes dropouts, but then I changed from WPA2 to WPA on my network, and that seems to have helped.

Perhaps when you switch it to 5 GHz the signal loss is so great that your Mac Pro can no longer receive the signal.
5 GHz signals do not move through physical objects as well as 2.4 GHz signals.

Airport Express Disappears From Network

I have my Mac connecting to my Airport Express (6.3 firmware) via a Netgear DG834G wireless router.
If I reset the Airport Express, then it can be seen by the Admin utility and iTunes, but will disappear after a short period of time ( say 10 minutes ).
However even when it is not visible to the Admin Utilities scan I can still connect to the AX by its IP address, reset it and it will re-aooear again for a short duration.
Any ideas?

Same problem here...and yes also after receiving a new router from my provider.
The weird thing however is that when I use Airfoil in combination with Winamp (or whatever media player) there are no problems at all.
So the problem is for me clearly related to iTunes and the admin utility.
When using iTunes I have exactly 1 hour and 17 minutes music.
I have however no idea if Airfoil has a different way of comunicating with the AX (name, IP address, protocol)

Airport express disappears from list of multiple speakers

Since upgrading Mac OS X (to 10.5.7) and iTunes (to 8.2) my airport express remote speakers have not been working as reliably: The remote speakers tend to disappear from the "multiple speakers" list when they haven't been used for a few minutes. This is extremely annoying and takes away from the otherwise very smooth operation of iTunes Remote.
The current workaround for this is to quit and restart iTunes. This is NOT a solution since it requires users to go to the computer that iTunes is running on and to intervene manually. The express is hanging off a wireless network set up on an Airport Extreme. Normally, I control iTunes remotely with my iPhone so I can change what's playing and so on.

New observation: the problem seems to depend on whether you have a WDS network. Things are working much better for me since I reconfigured my network. Previously I used the express to extend the network set up on the extreme. After changing things so the express is just hanging off the extreme's wireless network iTunes has not been losing the express or speakers anymore. In fact, I can unplug the speakers, move them to a different part of the house, and often I can just plug them back in and they start playing again. Every now and then I have to stop and start them but I can do it with Remote where before I had to go to the computer that iTunes is playing on.
Eventually I will be wanting to extend the network again to take the laptop outside on the decks since without WDS the network ends pretty close to the house's walls. I hope Apple will fix the original problem by then.

Airport Express not visable with Admin utility, but pingable and...

Can be seen when I search for it in the admin utility. The Airport has started dropping constantly, and sometimes itunes doesnt see it but the device remains 100% pingable at all times.
The green light is on, and its connected fine.
Any reason why windows has issues seeing it (and then itunes fails)
Thanks

I have this exact same problem. It's like something spontaneously just ceased to work inside the AE unit. I don't understand it.
I tried updating the firmware to 6.3 and updated Airport on the G4 to 4.2.1, but nothing has changed. If anything, the problem seems to have gotten worse (sometimes connecting -- > NEVER connecting).
All the forums I have read seem to think this problem has yet to be solved by Apple. They recommend downloading iStumbler or a utility to monitor your networks and keep them "alive" by constantly pinging with a low-level signal. That hasn't worked either.
Need expert advice, please.

Airport Express dropping from Airport Extreme

Everything worked until a few weeks ago when I updated the firmware on an old Airport Express. The expresses (I had 2) started dropping from the network.
I now have a new Airport Extreme, a new modem and a new Airport Express. The Express extends my network. The Express is 30 feet from my main house in a guest house. It is a direct line through the window through the sliding glass doors to the room with the Extreme. In the guesthouse the Express connects to the 2.4 Ghz with a transmit rate between 100 and 150. It works (like it is working now) and then it will drop off the network.
I thought it was conflicting with my security router, which I have completely unplugged to test the Apple network. It still dropped off after working for a while. Sometimes it drops while I am using the network; other times it drops when I am not using it.
I have tried:
setting the channel to different numbers.
hard rebooting everything and resetting up the network.
getting a new modem.
getting a new Express.
getting a new Extreme (had a Time Capsule).
had my cable line redone (the cable folks thought it was frayed and maybe that was the problem).
The Extreme is on WPA2 and is now on automatic channel (having tried fixed ones I am back to automatic).
I'm still having the problem.
Advice? Help or maybe I need to finally give up on Apple, which I have usually loved....

Thanks for your explicit comments iFelix.
No luck yet.
Here is where I stand:
- home wireless network: RedFoxNetwork
-->> Cable modem connected to Airport Extreme, router connected to Airport Extreme
-->> this Network hosts iMac G5 (with iTunes, Airport card), Mac Mini, Windoz XP Dell
-->> uses channel 11
--->> uses WEP
- 2nd network (RedFoxMusic) - as you suggested
-->> this network is hardwired from router above to Airport Express
-->> 2nd network configured as you suggested
---- do not Distribute IP
---- uses channel 2
---- iTunes speakers named "Living Room"
---- no WEP
So now I have 2 networks, RedFoxNetwork & RedFoxMusic, in the Airport menu bar selector on my iMac.
When the iMac is on the primary wireless network, TheRedFoxNetwork, I do not see "living Room" as a choice in the lower right speaker selector in iTunes. Playing music in iTunes produces no music from the living room (hard wired Airport Express connection).
Just for kicks, I select the RedFoxMusic network on the iMac. "Living Room" appears as a speaker choice, ITunes plays over Airport Express & stereo.
What have I missed that I needed to select the second (hardwired) network in order for AirTunes to work properly?
Thanks in advance.
Rob
As I said "never connect to the Airport Express
network", this means "never connect to the Airport
Express network".
If I create a second wireless network, then would
I
need to switch to the network supporting the
Airport
Express?
No
If not, the remote speakers would not
appear in the iTunes Speaker selection dropdown,
correct?
They will appear as the Airport Express is still part
of your network, in fact both wireless networks are
in fact one network, but you want iTunes to go via
the ethernet connection to avoid the dropouts.
Or does the wired connection obviate the need to
switch to the 2nd (iTunes only) network?
Yes.
Which is why I said "never connect to the Airport
Express network".

My Airport Express disappeared from my wi-fi network (again). How to get it back?

Using to stream iTunes to another room. Router DHCP table shows AE but APUtility doesn't find it. Grayed out in iTunes. This happens a couple times a year, suddenly. Very frustrating! When I connect by Ethernet works fine, so not hardware.

Make sure that you do not run Firefox in full screen mode (press F11 or Fn + F11 to toggle; Mac: command+Shift+F).
Press F10 or tap the Alt key to bring up the "Menu Bar" temporarily if the Menu Bar is hidden.

Where did my AEBS go??? AEBS disappears from AirPort Utility

I have set up my new AirPort Base Station using the Airport Utility but once it is setup it disappears from the utility. I am able to use the AEBS as an ethernet router for my mini HOWEVER my secondary MacBook is only able to "find" the wireless signal periodically. It is not a distance problem since the two computers and the routers are in the same small bedroom!
Any suggestions to improve performance? Reliability? I am beginning to think that I was better off with my not so fast Airport Extreme. . .

Thanks for the quick response! I will not discount the idea that I made a mistake in the setup but I have not duplicated any of the names or passwords in the setup.
I also thought that maybe there could have been that type of issue so I reset the AEBS and used the Airport Utility to set up the router again (it seems like whenever I setup a router at home it takes at least two tries before I get all the steps right. . . so it was not a big deal).
After completing Airport Utility on my mini everything looked great, then without any action on my part the AEBS DISAPPEARED from Airport Utility!!! It makes sense to me that if the utility cannot see the AEBS then the MacBook is going to have problems too. . .
Any other plans of action? My partner, the MacBook user, is voting for taking the **** thing back even though I am really liking the much faster ethernet connection. . .

I have Airport Extreme (802.11ac), which disappears from Airport Utility

Why does it disappear? I am not further than 50 feet from AE and it flips out! AE is connected to a switch from ISP located floor below my apartment that only works if set to "Bridge Mode" on network settings tab. I am trying to use connected 1TB drive to stream movies to AppleTV that is not 50 feet away from AE. When AE disappears from Airport Utility, I still have connectivity to web via Wi-Fi, but I cannot stream from HD. Very frustrating!!!! Running MBA with all software updated. Any thoughts?

Are you running Yosemite on your MBA? If so, this may be the culprit. There are a number of posts here describing this exact issue. At present there doesn't seem to be a solution. Even the latest OS X build 10.10.1 did not seem to resolve it. One theory going around is that this may be due to a conflict between the Bonjour protocol and the AirPort Utility. Some have tried temporarily disabling their OS X software firewall which appears to work ... BUT not consistently ... nor would I recommend it.

Apple Airport Express disappears

Hello,
I do not think you live in the Bermuda Triangle and it is normal that my Airport Express disappears No, unfortunately not.
I would like to use my AE to stream music, they've also integrated it with the Airport utility into an existing wireless network.
10min long this works well, music will play properly, then "disappear", AE, and I can not in iTunes, select speakers, yet she finds the Airport Utility.
Oddly enough, the pilot light is lit on the AE still green ie actually it should work.
I use a router ASUS RT-N56U and use Windows 7
Airport Utility software version 5.5.3
iTunes version 10.5.2.11
p.s. Sorry for my bad english, it comes from Google Translate german-englisch :-)

See if this doesn't help.

Trying to update airport express by downloading airport utility 5.6 on my macbook pro/lion. getting error message "version of OS X on this volume is not supported" What does it mean?

Trying to update airport express by downloading Airport Utility 5.6 (which it says I need). When installing I get an error message, "...version of Mac OSX on this volume is not supported." What does it mean/what do I do?

For OS X Lion, you need to download this version directly from Apple Support Downloads.

Airport icon disappeared from menu bar

For one of my two Users, the Airport icon disappeared from the menu bar. Now I cannot turn Airport on or off. Internet Connect only shows the internal modem. Restarting the computer did not solve the problem.
It has worked well until yesterday, all of a sudden the icon was gone. Airport Admin does work, and it restarts the base station when I change something (I changed the password just to test this). So the hardware is working.
If I log on as a different user, the icon is there, and everything works as normal. It therefore seems to be a set-up problem at one of the users.
I would appreciate any help on this one.
Thanks in advance,
Maarten

Maarten,
Welcome to Apple Discussions!
Go to Apple -> System Preferences -> Network. Select the AirPort Entry from the list of Network Devices, and click the "Configure..." button.
If not already there, navigate to the "AirPort" tab, and check the "Show AirPort status in menu bar" checkbox at the bottom of the window.
This should put it back up there.
Let me know if you need more help.

I just bought an AirPort express. Currently I have a qwest wired router plugged into the back of my computer via an ethernet cable. Can I just unplug the ethernet cable and plug it into the AirPort express, then use the setup utility?

I just bought an AirPort express. Currently I have a qwest wired router plugged into the back of my computer via an ethernet cable. Can I just unplug the ethernet cable and plug it into the AirPort express, then use the setup utility? Most of the discussions involve an existing wireless network. I don't have one.

Correct. That's the way to set up the AirPort Express. After connecting your AirPort Express to the router, open AirPort Utility (in /Applications/Utilities) and follow the steps

Renamed Airport Express with the Airport utility, but iTunes shows old name

I renamed my two Airport Expresses using the Airport Express utility because I have moved them in the house and the old names don't make sense anymore. In the AirPort Express utility, I can see the new names. However, iTunes (and Apple Remote on the iPhone) do not recognize these new names, they are still showing the old names. How can I get these devices to recognize the new names?

Actually I have solved my own problem. I hadn't realized that the Airport Utility has essentially two names for each Airport. There is the name of the device as the Airport Utility sees it, and then a different name called the iTunes Speaker name (look under manual setup in the Music area). This latter is the name that appears in iTunes. As soon as I changed this, iTunes recognized the new name.

Can't see Airport Express unit, nor Airport Express Setup in my Network Settings

I can see my Airport Express in the Airport Express Utility App, lights are all green, but I can't see the unit, nor see the Airport Express Setup section inside my Network Settings. This is the case when trying to find the WiFi signal from 3 MacBookPros, as well as my iPad and iPhone (all running latest OS versions). I've been through the screenshots on line about how easy this is supposed to be to set up, but I cannot see the Express units at all. Oh, and I've downloaded the firmware updates and recycled the unit. No change. Bad Unit?

Do you want the Express to create a wireless network?
How did you configure the Express to connect to the Internet, and how are you connecting to the Internet now?
Here are the instructions: http://manuals.info.apple.com/MANUALS/1000/MA1613/en_US/airport_express_80211n_2 nd_gen_setup_guide.pdf

Airport Express to extend Airport extreme

I am trying to extend my airport extreme with an airport express. Old airport express and not sure if 'n' or 'g'. When I first configured airport express I had the option to extend an existing network and all seemed well. When I reopened airport utilities to check settings my airport express was set to join a wireless network and there was no option to extend anymore. Do I need to try and set up a WDS? How can I find out if my airport express is n or g?
Thanks

You can configure a "g" AirPort Express to "join a wireless network", but it will not provide any additional wireless coverage in this type of setting. It is a wireless client only.
It is impossible to configure a "g" AirPort Express to "extend a wireless network"
You can confirm this by opening AirPort Utility and clicking Manual Setup for the Express
Click the Wireless tab just below the icons
What available settings do you see for Wireless Mode?
"Extend a wireless network" will not be there unless you have an "n" AirPort Express
